Http::withToken(): Adds a Bearer Token for authorization in the request headers.Most modern APIs return data in JSON format. Laravel simplifies handling JSON responses by providing a json() method.
In many real-world applications, you'll need to send data to the server using POST requests. Here's how to send form data using the Fetch API.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>POST Request with Fetch</title>
</head>
<body>
<form id="postDataForm">
<input type="text" id="title" placeholder="Enter title" required>
<input type="text" id="body" placeholder="Enter body" required>
<button type="submit">Submit</button>
</form>
<div id="postDataOutput"></div>
<script>
document.getElementById('postDataForm').addEventListener('submit', function(e) {
e.preventDefault();
const title = document.getElementById('title').value;
const body = document.getElementById('body').value;
fetch('https://jsonplaceholder.typicode.com/posts', {
method: 'POST',
headers: {
'Content-Type': 'application/json'
},
body: JSON.stringify({
title: title,
body: body
})
})
.then(response => response.json())
.then(data => {
document.getElementById('postDataOutput').innerHTML = `
<h3>Data Submitted:</h3>
<p>Title: ${data.title}</p>
<p>Body: ${data.body}</p>
`;
})
.catch(error => console.error('Error:', error));
});
</script>
</body>
</html>Next, you'll need to configure your database settings. Laravel uses environment variables to manage configuration, so you'll need to update the .env file in your project root.
Open .env and update the database configuration:
import 'package:flutter/material.dart';
import 'package:provider/provider.dart';
import '../providers/weather_provider.dart';
class WeatherScreen extends StatelessWidget {
@override
Widget build(BuildContext context) {
final weatherProvider = Provider.of<WeatherProvider>(context);
return Scaffold(
appBar: AppBar(
title: Text('Weather App'),
),
body: Center(
child: weatherProvider.weather == null
? Column(
mainAxisAlignment: MainAxisAlignment.center,
children: [
Text(
'Enter City Name',
style: TextStyle(fontSize: 24),
),
Padding(
padding: const EdgeInsets.all(16.0),
child: TextField(
onSubmitted: (value) {
weatherProvider.fetchWeather(value);
},
decoration: InputDecoration(
border: OutlineInputBorder(),
labelText: 'City',
),
),
),
],
)
: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: [
Text(
weatherProvider.weather!.cityName,
style: TextStyle(fontSize: 32, fontWeight: FontWeight.bold),
),
SizedBox(height: 16),
Text(
'${weatherProvider.weather!.temperature}°C',
style: TextStyle(fontSize: 56),
),
SizedBox(height: 16),
Image.network(
'http://openweathermap.org/img/wn/${weatherProvider.weather!.icon}@2x.png',
),
SizedBox(height: 16),
Text(
weatherProvider.weather!.description,
style: TextStyle(fontSize: 24),
),
],
),
),
);
}
